[0072] Embodiment 3:

[0073] The method for using the core placement device for drilling, in the drilling site, assembles the core placement device for drilling according to the process, and the specific operation further comprises the following steps:

[0074] Step S01: the geologist starts the first controller and the wireless charging transmitter, inputs the number of the core box tray 5 that needs to place the core to the first controller, the first controller sends a signal to the first stepper motor 6, the first controller drives the first stepper motor 6 to rotate, the gears 4 connected with the driving shaft of the first stepper motor 6 rotate, drive the chain 3 engaged with them to walk synchronously, and at the same time, the chain 3 drives other gears 4 engaged with it to rotate synchronously, and the plurality of core box trays 5 fixed on the chain 3 through the load balancing mechanism walk synchronously with the chain 3;

[0075] Step S02: when the chain 3 walks along a straight line, the rotating shaft of the load balancing mechanism is stationary relative to the sleeve, the core box tray 5 remains horizontal under the action of its own gravity; when the chain 3 passes through the gears 4 and is bent, the rotating shaft of the load balancing mechanism rotates a certain angle with the bending of the chain 3, the sleeve is rotatably sleeved on the rotating shaft, the sleeve remains stationary relative to the core box tray 5, and the core box tray 5 still remains horizontal as a whole under the action of gravity; the wireless charging receiving unit of the second controller below the core box tray 5 receives the wireless charging of the wireless charging transmitter, powers the electric control balancing device, and at the same time feeds back the position signal of the core box tray 5, and the first controller judges whether the core box tray 5 that needs to place the core reaches the predetermined position according to the position signal of the core box tray 5;

[0076] Step S03: when the first controller judges that the core box tray 5 selected by the geologist that needs to place the core walks close to the predetermined position, the first controller sends a signal to make the stepper motor 6 brake gradually, when the gears 4 stop rotating, the chain 3 also stops walking, the core box tray 5 selected by the geologist stops at the predetermined position, and the geologist places the core box full of core on the upper surface of the core box tray 5;

[0077] Step S04: repeat steps S01 to S03 until the core box tray 5 is fully placed with core boxes;

[0078] Step S05: When the geologist needs to make a geological record, the geologist inputs the number of the core box tray 5 that needs to be recorded on the first controller, and the first controller sends a signal to the first stepper motor 6, which drives the first stepper motor 6 to rotate, causing the gear 4 connected to the first stepper motor 6 drive shaft to rotate, driving the chain 3 to walk synchronously, while the chain 3 drives other meshed gears 4 to rotate synchronously, and multiple core box trays 5 fixed on the chain 3 walk synchronously with the chain 3. When the first controller determines that the core box tray 5 selected by the geologist is approaching the predetermined geological recording position, the first controller sends a signal to gradually brake the stepper motor 6, stop the gear 4 from rotating, and the chain 3 also stops walking, the core box tray 5 selected by the geologist stops at the predetermined geological recording position, and the geologist takes out the core box on the core box tray 5 to make a geological record of the core;

[0079] Step S06: When the geologist takes out or returns the core box, the overall center of gravity of the core box tray 5 will change during the process of adding or reducing the weight of the core box, causing the corresponding core box tray 5 to tilt under the gravity of the overall center of gravity; The angle sensor 12 under the core box tray 5 monitors the tilt direction and angle of the core box tray 5 every 2-5 seconds, and transmits the tilt direction and angle of the core box tray 5 to the second controller.

[0080] When the tilt angle of the core box tray 5 is less than or equal to 30°, the second controller starts the second stepper motor 9 to drive the corresponding screw rod 10 in the opposite direction of the tilt direction of the core box tray 5 to rotate, driving the corresponding counterweight 11 to move towards the edge of the core box tray 5 opposite to the tilt direction of the core box tray 5, until the tilt angle measured by the angle sensor 12 approaches 0°, and the second controller stops driving the second stepper motor 9 to rotate, balancing the overall center of gravity to avoid the core box tray 5 from tipping over due to excessive tilting.

[0081] When the core box tray 5 is inclined at an angle greater than 30°, the second controller starts two second step motors 9, one of the second step motors 9 drives the corresponding screw rod 10 in the opposite direction of the inclination direction of the core box tray 5 to move the corresponding counterweight 11 to the edge of the core box tray 5 in the opposite direction of the inclination direction of the core box tray 5, at the same time, the other second step motor 9 drives the corresponding screw rod 10 in the same direction of the inclination direction of the core box tray 5 to move the other corresponding counterweight 11 to the center of the core box tray 5, until the angle sensor 12 measures the inclination angle close to 0°, stop the two second controllers driving the two second step motors 9 to rotate, balance the overall gravity center by moving the two counterweights 11 to avoid the core box tray 5 from falling due to excessive inclination;

[0082] Step S07: repeat the execution of steps S05 to S06 until the cores on the core box tray 5 are all recorded according to the needs.

A method of using a drilling core placement device as claimed in any one of claims 1-8, characterized in that, In the drilling construction site, the drilling core placing device is assembled according to the process, and the specific operation further includes the following steps: Step S01: the geologist starts the first controller and the wireless charging transmitter, inputs the number of the core box tray (5) which needs to place the core to the first controller, the first controller sends a signal to the first stepper motor (6), the first controller drives the first stepper motor (6) to rotate, the gear (4) connected with the driving shaft of the first stepper motor (6) rotates, drives the chain (3) engaged with it to walk synchronously, at the same time, the chain (3) drives other meshed gears (4) to rotate synchronously, and a plurality of core box trays (5) fixed on the chain (3) through the load balancing mechanism walk synchronously with the chain (3); Step S02: when the chain (3) walks along a straight line, the rotating shaft of the load balancing mechanism is stationary relative to the sleeve, the core box tray (5) remains horizontal under the action of its own gravity; when the chain (3) is bent through the gear (4), the rotating shaft of the load balancing mechanism rotates a certain angle with the bending of the chain (3), the sleeve is rotatably sleeved on the rotating shaft, the sleeve remains stationary relative to the core box tray (5), and the core box tray (5) still remains horizontal as a whole under the action of gravity; the wireless charging receiving unit of the second controller below the core box tray (5) receives the wireless charging of the wireless charging transmitter, and powers the electric control balancing device, while feeding back the position signal of the core box tray (5), the first controller judges whether the core box tray (5) which needs to place the core reaches the predetermined position according to the position signal of the core box tray (5); Step S03: when the first controller judges that the core box tray (5) selected by the geologist needs to place the core and walks close to the predetermined position, the first controller sends a signal to make the stepper motor (6) brake gradually, when the gear (4) stops rotating, the chain (3) also stops walking, the core box tray (5) selected by the geologist stops at the predetermined position, and the geologist places the core box full of rock core on the upper surface of the core box tray (5). Step S04: Repeat steps S01 to S03 until the core box tray (5) is fully placed with core boxes; Step S05: When the geologist needs to make a geological record, the geologist inputs the number of the core box tray (5) that needs to be recorded on the first controller, and the first controller sends a signal to the first stepper motor (6). The first controller drives the first stepper motor (6) to rotate, and the gear (4) connected to the drive shaft of the first stepper motor (6) rotates, driving the chain (3) engaged with it to walk synchronously. At the same time, the chain (3) drives other meshed gears (4) to rotate synchronously, and multiple core box trays (5) fixed on the chain (3) walk synchronously with the chain (3). When the first controller determines that the core box tray (5) selected by the geologist approaches the predetermined geological recording position, the first controller sends a signal to gradually brake the stepper motor (6), stop the gear (4) from rotating, and stop the chain (3) from walking. The core box tray (5) selected by the geologist stops at the predetermined geological recording position, and the geologist takes out the core box on the core box tray (5) to make a geological record of the core; Step S06: When the geologist takes out or returns the core box, the overall center of gravity of the core box tray (5) will change during the process of adding or reducing the weight of the core box, causing the corresponding core box tray (5) to tilt under the gravity of the overall center of gravity. The angle sensor (12) under the core box tray (5) sends the tilt direction and tilt angle of the core box tray (5) to the second controller in time. The second controller starts the second stepper motor (9) to drive the screw (10) to rotate, and then drives the corresponding counterweight (11) to move until the tilt angle measured by the angle sensor (12) approaches 0°. Stop the second controller from driving the second stepper motor (9) to rotate, and balance the overall center of gravity to avoid the core box tray (5) from tipping over due to excessive tilting; When the tilt angle of the core box tray (5) is small, the second controller starts the second stepper motor (9) to drive the corresponding screw (10) in the opposite direction of the tilt direction of the core box tray (5) to rotate, driving the corresponding counterweight (11) to move towards the edge of the core box tray (5) in the opposite direction of the tilt direction of the core box tray (5). Until the tilt angle measured by the angle sensor (12) approaches 0°, stop the second controller from driving the second stepper motor (9) to rotate, and balance the overall center of gravity to avoid the core box tray (5) from tipping over due to excessive tilting; When the core box tray (5) is inclined at a large angle, the second controller starts two second stepping motors (9), one second stepping motor (9) drives the corresponding screw rod (10) in the opposite direction of the inclination direction of the core box tray (5) to rotate, and drives the corresponding counterweight (11) to move to the edge of the core box tray (5) in the opposite direction of the inclination direction of the core box tray (5), at the same time, the other second stepping motor (9) drives the corresponding other screw rod (10) in the same direction of the inclination direction of the core box tray (5) to rotate, and drives the corresponding other counterweight (11) to move to the center of the core box tray (5), until the inclination angle measured by the angle sensor (12) approaches 0°, and the two second controllers stop driving the two second stepping motors (9) to rotate, and the overall gravity center is balanced by moving the two counterweights (11) to avoid the core box tray (5) from being tilted due to excessive inclination; Step S07: repeat steps S05 to S06 until all the cores on the core box tray (5) are completed according to the geological recording requirements.
